Thank you for the opportunity to help you with your question!
In a debate between whether a patient needs formal long-term care or informal care, the deciding factor is the amount of damage and recovery time. If a health situation can be handled within a 24 hour period, I believe that it should be followed through in an informal care maner; however, if a patient has a critical disease or pathology that will take longer than that 24 hour period, they should be refered to formal long term care.
Please let me know if you need any clarification. I'm always happy to answer your questions.
